Best Static Drop for '67 SWB stepper?

[ShredSled]

I'm currently pondering over the CPP set-up...
looking at around a 5/7 drop (is it even possible to go lower on a static susp.?) to put on a '67 SWB step-side that will be on 17" wheels with ~28" tires up front and probably 29" tires out back.

Currently looking hard at the CPP front upper and lower control arms (apparantly have better geometry for low ride-height, and hoping but unsure, that they may help center the wheels in the lowered wheel well better, anyone confirm?), and will go along with their modular 2" drop spindles and some 3" front drop springs and shocks and double shear shock brace. Rear would be center cross-member with tubular trailing arms and bolt-in frame notch with, can't decide, either 5" drop spring and 2" blocks, or 6" spring (CPP doesn't list one, but saw one from ECE) and 1" block, along with the proper shocks and relocators and deluxe track bar.

So what's the consensus on the set-up, or one like it? I did a quick search here, but nothing showed up on that complete kit, although I did find a nice article on it on some website magazine...

I've got to ask, is anyone else here running it like that?
Worth the coin to do a static suspension like that?

Are there any other companies that sell competetive components?
Most all high end stuff I see is for bagged configurations only, such as Porterbuilt, where I was looking at their x-member and trailing arms, as well as control arms, but they seem to be only for bags... wait time and cost might drive me away from getting those to work with a static drop.

Give me some input, let's hear what you've all got to say!
Thanks!
